Frost Hex (Blue)

If you have multiple Frostbites in play, each Frostbite triggers (for each Frost Hex) as a separate instance of arcane damage and can all be prevented with a single instance of arcane barrier 1.

Even if the Frostbite tokens are destroyed first during the end phase, the triggered effects still resolve and deal arcane damage, as triggered effects are independent of their source once they’ve been triggered.
